Aluminum-chromium solid solution brick for copper smelting furnace and manufacturing method
The invention discloses an aluminum-chromium solid solution brick for a copper smelting furnace and a manufacturing method, and the aluminum-chromium solid solution brick comprises the following raw materials in molar percentage: 48%-53% of compact white corundum, 20%-25% of brown corundum, 8%-12% of Indian chromium concentrate, 10%-15% of chromium oxide green, 5%-8% of alpha-Al2O3 and 3%-4% of a binding agent; and the method comprises the following steps: mixing the raw materials, feeding the mixed raw materials to a press machine for pressing to obtain a green brick, and firing the green brick in a kiln to obtain a finished product. The refractory material is prepared from the raw materials with aluminum and chromium as main bodies through proportioning, compression molding and firing, the problem that in the prior art, a refractory material is too fast in erosion and low in strength, so that the service life of a kiln is short is solved, the materials used by the product are low in cost and convenient to manufacture, the processing cost is greatly reduced, and the product yield is increased.
本申请公开了一种炼铜炉用铝铬固溶体砖及制造方法，以摩尔百分比表示，所述铝铬固溶体砖的原料包括：致密白刚玉48％‑53％，棕刚玉20％‑25％，印度铬精矿8％‑12％，氧化铬绿10％‑15％，α‑Al2O3 5％‑8％和结合剂3％‑4％；方法包括将原料混合、将混合后的原料送至压力机压型，得到砖坯、将砖坯入窑烧制，得到成品。本申请通过采用以铝、铬为主体的原料经过配比、压制成型、烧制而成，改善了现有技术中耐火材料侵蚀过快、强度不高导致的窑炉使用周期短的问题，并且本申请的产品所用的材料成本低廉、便于制造，极大降低了加工成本、提高了产品产量。
